There is no need to be a grammar police for this. Yes you can warn him/her if (s)he makes a grammar mistake but you shouldn't do this over and over. Because after a while he may really feel discouraged.

This is what i was trying to say. No need to be a grammar police, just say them their English is not good at all and they will try or not try to correct it. Not your mistake if they don't.
